I would also look into chiropractic adjustment; someone who is certified with the Webster technique, which will help stretch your ligaments and muscles around the uterus causing no harm to baby or you. This will give baby more wiggle room and also will eleviate the tightness that contributes to back pain and a whole host of health problems. I know of several great Drs around the Chicagoland area and surrounding suburbs if you are interested. You can contact me off list.
